The basic free plan for businesses offers very limited features: there is no option to create your own design and no convenient integrations with messengers. In fact, it's better to switch to the Pro plan right away and set everything up in your own style. However, the question of whether the Business plan is necessary remains open. For less money, you can create a full-fledged website on quality hosting, add payment processing and analytics, all without needing programming knowledge, just like with Taplink. If your sales are not solely tied to Instagram, then Taplink is unlikely to be the optimal choice in terms of price and functionality.
